ROTARY BLOTTER.

SPECIFICATION forming part of Letters Patent No. 434,135, dated August 12, 1890.

Application filed February 3, 1890- Serial No. 339,074; (No model.)

To all whom it may concern:

Be it known that I, EDWARD E. PARK, a citizen of the United States, residing in the city and county of San Francisco, State of California, have invented an Improvement in R0- tary Blotters; and I hereby declare the following to be a full, clear, and exact description of the same.

My invention relates to an improved device to be used as an ink-blotter.

It consists of one or more cylinders, built up of endless tubular sheets of blotting paper or material increasing in diameter, so that each exterior tube may be slipped over the interior ones, and in a frame-Work in which one or more of said devices may be journaled, as will be more fully explained by reference to the accompanying drawings, in which- Figure 1 is an end view of one form of construction of my device. Fig. 2 is a longitudinal vertical sect-ion ofthe same. Fig. 3 shows another construction of my device. Fig. at is a view of one of the endless tubular sheets.

In the construction of my improved blotter I take a central core or cylinder A, which may be made of wood or other suitable material, and upon the outside of this I fit a series of cylinders 13, made of absorbent paper or other suitable material for blotting purposes. These cylinders are molded in endless form, so as to present no projection or protuberance at any point, the inner ones being of a size to slip over the core A, and each succeeding endless tube being made of sufficiently larger diameterto be slipped over the preceding one until any suitable or desired diameter is obtained.

In the center of each end of the interior core A is made a hole or socket for the purpose. of receiving the pins G, which project inwardly from the elastic sides of the frame D. This frame may be made of any suitable material and in any suitable or desired form, and is preferably provided with a handle at E, by which it may be conveniently used. The ends of the frame are sufficiently elastic, so that they may be drawn apart for the purpose of placing the frame over the roller, and when released the centers or pivots Owill enter the holes or sockets in the ends of the core A,

and the latter, with its surrounding blotting cylinder,wil1 rotate freely upon the pivot-pins.

By taking the device in the hand the roller may be caused to rotate over any surface which it is desired to operate upon.

In the construction of my improved blotter I have found it preferable to make two of the blottingcylinders B built up about the cores A, as above described, and at the lower ends of the elastic sides of the frame are fitted transverse bars F, each of which has a pivot-pin 0, adapted to enter the end of one of the cores of the cylinders, there being twoof these pivot-pins at each end of the frame. It will be manifest that two of the cylinders would be supported side by side, and it will be only necessary to push the device over the surface from which the ink or other material is to be absorbed, and the rollers following one another will do the work in a neat and cleanly manner. \Vhenever the superficial porous tube has become so much saturated that it ceases to be of use, it is only necessary to cut it with a knife and remove it, when a fresh surface will be presented,which will be" used in like manner until worn out. These cylinders being made in quantity can be supplied to the trade, and it is only necessary to purchase them and introduce them into the handles or holders whenever necessary.

Having thus described my invention, whatI claim as new, and desire to secure by Letters Patent, is

An improved blotter consisting of two parallel cylinders, each composed of a central core and a series of independent tubes of molded absorbent material, said tubes being of increasing diameters, whereby one tube may be slipped endwise upon the other, and a frame having elastic or separable ends with transverse bars uniting the cylinders and.

having pivots adapted to enter sockets in the cylinder-cores, substantially as herein described.

In Witness whereof I have hereunto set my hand.

EDWARD E. PARK.
